Workstation Precautions
Use the following grounding precautions at workstations:
■
Cover the workstation with approved static-dissipative material (refer to Table 4-2
later in this chapter).
■
Use a wrist strap connected to a properly grounded work surface and use properly
grounded tools and equipment.
■
Use field service tools, such as cutters, screwdrivers, and vacuums that are
conductive.
■
When using fixtures that must directly contact dissipative surfaces, use fixtures made
of static-safe materials only.
■
Keep work area free of nonconductive materials such as ordinary plastic assembly
aids and Styrofoam.
■
Handle electrostatic-sensitive components, parts, and assemblies by the case or PCM
laminate. Handle them only at static-free workstations.
■
Avoid contact with pins, leads, or circuitry.
■
Turn off power and input signals before inserting or removing connectors or test
equipment.
